How to set max width of UIBarButtonItem

Question

I have a UIBarButtonItem in a UIToolbar that updates with a change in the name represented by the text box. The text field should not have a short maximum length. When the title is quite long, the element covers the button elements on the right. How can I make it automatically crop to a specific width?

Answer 1

Use a custom view with the widest possible width, textAlignment set to UITextAlignmentCenter and lineBreakMode to UILineBreakModeTailTruncation .

 UILabel* l = [[[UILabel alloc]initWithFrame:CGRectMake(0, 0, 200, 20)]autorelease]; //200 is just a number I choose. you should calculate your maximum possible value l.textAlignment = UITextAlignmentCenter; l.lineBreakMode = UILineBreakModeTailTruncation; self.navigationItem.titleView = l; 

Answer 2

You can also set the width in the Storyboard Size Inspector:
